My invention relates to wood-saw attachments for automobiles and more especially 5 Another object of my invention is to providb a. wood saw capable of being driven by -therein wheels of sin-automobile and espe- H a wood saw in which the rear wheels of e automobile will be held in engagement the wheels by especially constructed Another-object of my invention is to prohas in a wood saw attachment for automohfls, meansfor raising the rear wheels from i I theground and pressing said wheels into encut with pulleys located on the attfifi ent for driving the saw located on the saidattachment. I

Another object of m invention is to pro- .2 at; means to positive y hold the wheels of the automobile in enga ementwith the pullays locatedon the woo saw.

Another object of myinvention is to provid a Wood saw which can be quickly atll itached to an automobile for transport and uickly attached to the wheels of the autonrtibile when it is desired to apply power to the saw.

'- Having thus stated some of the objects of it! my invention, a brief description of the different figures in the drawings will now be .given. 7

Figural is a side elevation of my dev ce,

. shown the wheels of an automobile raised 33 fr the ground and held in engagement wig? the pulleys;

igure 2 is a plan view of my device; Figure 3 is a detail view of the notched rack for securing the wheels on the automobile inany desired position.

A brief description of the different figures in the'dra having been a detailed description of the drawings will now be given, in which like reference characters I represent corresponding parts thruout the drawings.

. The numeral 1 indicates the rear wheel of a an automobile, while 2 represents the housing for the rear axle of an automobile. The

so numeral 3 represents the front cross-piece of the device, and extendin rearwardly at right angles from the mem r 3 are the side members 4 and 5, and these side members 1927. Serial No. 231,963.

9 and 5 and there is secured the cross member 11. I V

At the lowermost portion of the supports 9 and 10 there are. securedthe braces12. These braces extend forwardly and connect with the side members 4 and 5 at the point 15.

Secured to the member 3 and extending rearwardly to the cross-member 6 and being secured thereto; are the members 13 and 14;, the purpose of said members will'be presently explained.

The cross-member 3 has alongitudinally extending member 16 secured to its central portion, said member 16 having holes17 and 18 therein, for receiving any desired means for attaching the device to an automobile for transport purposes.

Secured to the junction point of the mem- AND 'HANUFAC'I'UBING GOIPANY, O!'*GBEENSBURO, NORTH Cmml; A GOEPOIILTIONOFNORTH CAROLINA.-

bers 9 and 12 and also to the junction point of the members 10'and 13 are bearings20 in which the axle 21 is mounted. On the ends of this axle are the wheels 22 and 23.

Near the junction point of the members 4 j and 9 and also at the junction point of the members 5 and 10, are secured the bear-in s 25 and 24 in which the shaft 26 is rotata y mounted. This shaft has awpulley 27 secured on one of its ends, and has the saw 28 .secured to the opposite end from the pulley.

Secured to the ends of the members 6 and 7 are the members 30 and 31. Near thecentral portion of each'of the members-30 and 31 are mounted the bearings 32 and 33 for the reception of the shaft 34. The shaft 34 has pulleys 35 and 36 mounted on each of its ends and rigidly secured thereto to rotate therewith. The pulley 37 is also secured to the shaft 34 to rotate therewith and is secured on said shaft at a point inwardly from the pulley 36 and outwardly from the mem- Secured to the member 6 is an upstandin member receivin the bolt 41. This'bolt 41 serves as a pivot or the weight pulle frame 42, holding the weight pulley 43. 11 endless belt runs over the pulleys 37 and 27, and serves to drive the saw when the wheels of the automobile are brought into engagement with the pulleys and 36.

The means for lifting the wheels of the automobile from the ground and pressing them a ainst the pulleys 35 and 36 comprises t e following The levers 44 and 45 are pivoted on the bolts 46 and 47, the said levers having 11 standing portions 49 on their forward en s.

The upstanding portions have notches 48 in their upper surfaces for the reception of the housing 2. The rearmost portions of the members 44 and 45 have members 50 pivotally secured thereto by means of the bolt 53. These members 50 have notches 51 therein for engagement with the bolt in the members 4 and 5 when the levers 44 and 45 are pressed down to the desired point.

The members 50 also have the notches 54 for engagement with the bolt 55 to hold the levers 44 and 45 in raised position when it is desired to remove the wood saw from enagement with the wheels of the automobile for transportation from one place to another. A saw table 56 is pivotally mounted on the axle 21, and is held in limited space by means of the chain 57.

The method of operation is as follows: The device is rolled underneath the rear end of an automobile to'a point where the notches 48 will engage the housing for the rear axle when the levers 44 and 45 are pressed downwardly at their rear ends. When the said levers are pressed downwardly at their rear ends the notches 48 will engage the housing for the rear axle-and wil cause the rear wheel on the side on which the lever'is depressed to be pressed against one of the pulleys 35 or 36. The lever on the opposite side will be depressed, and the device will assume the position shown in full lines in Figure 1, and when the motor runs with the clutch in gear power will be imparted to the saw thru the means above described.

-Having thus fully described my invention, what I desire to protect and secure by Letters Patent is: 1. In a power take-off means, an L- shaped inverted frame, wheels secured to the ends of the shorter legs of the said frame, a

cross-piece secured to the end of the longer an automobile, levers secured to the-framework, notches in the forward portions of the leversadapted to engage the lower side of the rear axle of the automobile, the levers being adapted to raise the rear wheels of the automobile and press them upwardly and rearwardly into engagement with the pulleys located on one of the rotatable shafts mounted in the frame, both of said shafts -being connected together for rotation, work performing means in operative connection with one of said shafts, both of said shafts being located at a point above the horizontal plane of the rear axle of the automobile.

2. A woodsaw attachment for automobiles comprising a rectangular frame, asup'porting member secured to the forward portion of the frame, legs secured to the rear portion' of the frame, wheels mounted on the lower ends of'the legs, said legs and wheels being adapted to give the rectangular frame a forward incline, parallel rotatable shafts mounted'in the frame, pulleys mounted on one of the'shafts, work performing means mounted on the other shaft, said shafts being connected together'for rotation, levers pivoted in the rectangular frame, notches in the forward portions of thelevers adapted to engage the rear axle of the automobile, ad usting and holding means located on the other end portions of the levers, the levers being adapted to raise the rear wheels of the automobile and to press them rearwardly and upwardly against the pulleys mounted on the ends of one of the shafts, both of the parallel shafts being mounted at a point above a horizontal plane passing through the rear axle of the automobile, the relation and position of the parts being adapted to cause the structure when attached to the rear wheels of an automobile to form an inseparable partthereof until the operator desires to separate the frame from the automobile.

In testimony that I claim the foregoing as my own I hereby afiix my signature this the 2nd day of November, 1927.
